A hydrogen atom in ground state absorbs 10.2 eV of energy. The orbital angular momentum of the electron in increased by

Question

Philoid · Accepted Answer

We know, according to Bohr’s Model, the energy ∆E released, when electrons move from n₂ energy level to n₁ energy level is given by,

For hydrogen atom, Z=1 and given ∆E=10.2 and n₁=1. Let n₂=n (say).

Thus,

Thus, the increase in angular momentum is given by,

Or

Hence, option (a) is the correct answer.
